Valerie - I bought a kit at Hobby Lobby for like $8 that had the clamp and some precut wire with instructions. I really bought it for the instructions. They were detailed and I did the woven bracelet quite easily. Now that I know what I am doing, and I have the clamp, I am going to try more with my own wire. The instructions also have some different options.
So if there is a Hobby Lobby near you, you might check it out. At the HL near me, they are located by the chain maille kits.
Now that I have found this, I would love some more details about different weaves as well. At the craft shows that I go to, there is nothing like this. So this might be that something different I was looking for.
